More Information
Summary:A file system cloning method and apparatus is provided. In the method, a destination storage system first receives first information from a source storage system in which a file system runs. The first information is used to indicate a data layout of the file system. Then, the destination storage system creates a cloned file system of the file system based on the first information. After the destination storage system creates the cloned file system corresponding to the file system in the source storage system, an application running on the file system in the source storage system can also run on the cloned file system. Only a data layout of a source file system is required for creating the cloned file system. In other words, data of a file included in the file system does not need to be transmitted, and an amount of data in the data layout is less than an amount of data included in the file. In this way, a delay in an application migration process can be reduced.
